FLASH DEVICE.

i Application led July 5,

To all @f2/710m t may concern:

it known that BAXTER Ocrnm'citizen of the United States of America, residing` at Youngstown, in the county y of Mahoning and fitate oie lhio, has invented certain new and .iseiiul improvements in Flash YDevices, ol which the 'following is a speciiication.

` This invention relates to an improvement in flash machines, preferably for photographic uses7 and the object thereof is to provide a construction which includes a number oi receptacles receivingthe materials for producing the ilash, together with suitable mechanism for causing the mate'-V riais in each receptacle to be ignited in turn in a positive and certain manner when the camera. shutter is thrown open to make the exposure Jfor a picture that is to be taken.

Reference is to be had to the accompany. ing drawings forming a part of thespecification,y in which the same characters of reference indicate the same parts `in all the views.

Figure 1 is a perspective view of an ordinary iiash cabinet with my flash 'machine installed in the back of the same.

Figure 2 is a plan of the wiring showing the position ot' transformer and? spark coil', Figure is a detail view showing 'atop plan view of the flash machine without the flash cabinet. Figure 4 is a rear elevation of the flash machine. j Y

Figure 5 is a side elevation ot the flash machine.

Figure 6 is a detail viewshowing operat- A ing lever and connecting parts.Y

Figure 7 is a detail view showing action of a dog for holding a disc in a iXed relation in reference to other parts `of the machine.

My invention comprises a rotating plate or disc 1 which carries mounted around the periphery thereof a plurality of recesses 2 formed within primary recesses 3. These primary recesses 3-are formed with side walls 4i formed so as to provide a shut-ter for .closing openings 5 in ai vertical wallY portion 6 to which the mechanical elements oi the device are attached.

e By referring to Figure 3 it will be seen that one of the plurality ofrecesses 2 is di rectly underneath V-a'n elect-rode 7 so that when a spark is caused to jump from Ythis Y electrode T through the recesses2 'forming the etha. eiectrcde, any Hash compound res 1922,. Serial No. 572,926A

tained within the recesses 2 will be ignited. TSilben thisiiash takes place the side walls @L close the openings 5, thereby eliminating the possibility of the flash compounds in the other recesses 2 from igniting. `(See Figure 1.)

By referring to Figure 5 it willbe seen that l have provided an upperE bracket. 8 and a lower bracket 9 for the support of vertical spindle 10 carrying the rotating plate orv disc 1 at its upper end. "Directly underneath the upper bracket 8 there is mounted upon the spindle 10 a small disc 11 provided with a plurality of Vshaped notches 12 correspondingy with the plurality of recesses`2 in a plate or disc 1. Attached to this upper bracket 8 is a keeper 13 secured by means of bolt 14. The lzeeperl is preferably made of flat spring steel with an Vouter end 15 termed to engage in the 1l-shaped notches 12. n

In operating this device the `operator moves the handle 16 clockwise, thereby rotating the vertical spindle 10y by means of a 'ratchet 17 mounted upon said verticalV rality of recesses2, when the keeper 13 holds the spindle from undesired rotationV until the operator wishes to advance the next recess 2 containing a flash compound. When the. operator releases the handle' 16 a coil spring 2O attached to an arm 21 and to the handle 16 pulls the handle k16 back into starting position. Directly underneath the plate or disc 1 and attached to the vertical wall portion 6 by means of bolts 22 is a *housing 23 provided with a slot 241 for the Vproiection of theV handle 16.

By referring to Figures 2 and Llitho manner of carrying the electric current may be understood.` Fignre 2 shows incoming wires 25 kwhich may be carrying 110 volts, such as is ycommon in operating lights in house lightingn etc. These incoming wires 25 are connected to a transformer 26. Leading from this transformer 26 there is a wire 27' connecting to a spark coil 28 which has a wire 29 leading to the electrode 7. Also leadingirom the spark coil 28 there is a wire 30 leading to the plate or disc 1 which is preferabiy made of steel in order to form a secend electrode; the photographer i causes bv any means the opening of the fit) shutter of his camera7 the simultaneous contact of the Wires B1 and 32 takes place, this completing the circuit and causing a spa-rk to jump between the electrode 7 and `the recesses 2 in a metallic plate or `disc l, thereby igniting the flash coimpoundin said recess 2.

By referring to Figures l and 4 it will be seen that I have provided arectangular door 33 carrying the ,electrode 7 so that when desiredaccess to the interior ot the cabinet 34: may be secured. This cabinet Blinay beet ordinary construction, and .this particular part of the device is not claimed as new.

Byleferring to Figure 4 it will be seen that I have constructed a vertical Wall portion .6 in tvroparts securedtogether by means of movable cleats 35. The purpose 'of having the verticalwall portion 6 made in two parts is for ease in ,assembling and constructiono-f openings 5.

Byireferring toI Figures l, 3, l and 5v it will be seen that the rectangular door 83 supports the electrode 7. By placing the clasps 36 in avertical position, the operator may remove the rectangular door 33 bygrasping the vknob 37. The principal reason tor constructing the rectangular ydoor ,33 infthis device is in order to remove the electrodevforcleaning.

,referring to Figure 3 itk will ,be `seen that .l lhave provided ,a metallic ,plate which ,comes ,in .contact -With thefmetallic plate 39, Which isin turn connected with Wire 29, (see Figure 4).

What I vvclaim is: n

l. In aA flash machine, thecombination .of a revolving plate, aplurality of primary recesses, a plurality ot recesses formed Withinsaid primary recesses, a verticalwall portion. of a lasli cabinet, means for closing openings in said vertical Wall portion so as to eliminate danger ,vof the flash from igniting flash. compounds in other receptacles ,of aY revolving ,plate which are back ot' -saidvere tical ,Wall lportioman electrode positioned above a recess for containingzflash powders, a second electrode connectingsaid disc, means for causing a spark t0 jump between said electrodes, means for rotating said disc, means Ifor holding said disc from undesirable rotation, substantially as described for the purpose set forth.

`2. ,Ina device of Athe class described, a vertical Wall portion forming the rear portion of a flash cabinet, supported to vsaid vertical Wall portion tivo brackets, said brackets supportinga vertical spindle, said spindle carrying upon its upperl endarevolving disc, said disc projectingpartly `through said vertical wall portion, a ratchet `secured to said Vertical spindle, an operatinghandle mounted uponesaid vertical .spindle carryingya dog' functioning with said ratchet, means Jfor automatically returning said handle to, starting positionna disc secured tosaid vertical spindle, ,V-,shaped notches tormed yon ithe outericireumference of saiddisc, aspring keeper positioned so ,as to functionI in said V- shaped notches, :substantially as described for the purpose Vset forth.
